Background and Objective: Due to the low cost in a long-term application and environmental friendliness, the use of biological remediation has gained significant attention in recent decades. This study aimed to investigate the use of ornamental plants and arbuscular mycorrhizal fungi (AMF) for phytoremediation of lead contaminated soil under greenhouse conditions.
Methods: The research was conducted as a factorial in a completely randomized design with three factors of plant type including gladiolus (Gladiolus grandiflorus), ornamental cabbage (Brassica oleracea), marigold (Tagetes erecta), lead concentration (0, 25, 50, 100 and 200 mg kg–1) and fungus (with/without AMF) in three replications. Harvesting was carried out after the plants reached the flowering stage. The concentrations of lead in plant tissues and soil, uptake, bioaccumulation factor (BCF), transfer factor (TF) of lead and plant growth traits were measured.
Results: The Pb concentration in the root and shoot of ornamental plants increased significantly due to the increase in soil Pb concentration. The root Pb concentrations were about 2 to 4 times greater than its shoot concentrations (at different Pb levels). The TF values for Pb in all plants were less than one. The AMF inoculation significantly increased shoot and root dry weights of G. grandiflorus and B. oleracea under lead stress. Besides, the AMF inoculation significantly increased Pb concentration, uptake and root BCFs of all three ornamental plants compared to non-inoculated treatments. The root BCFs of all ornamental plants were greater than one, but no significant difference was observed across its values within the three plants.
Conclusion: Overall, the results showed that arbuscular mycorrhizal fungi modulate metal accumulation and physiological traits differently in the studied ornamental plants.
